Air dry clay is a fantastic, beginner-friendly medium that opens the door to endless creative possibilities. Whether you’re crafting home decor, ornaments, embellishments for mixed media art, or just having fun, pairing air dry clay with decorative moulds can elevate your projects beautifully.
If you’re new to this technique, don’t worry! Below are some tried-and-true tips to help you get clean, detailed results with ease.

Silicone molds can be used for a variety of projects, including making a beautiful French inspired wall, updating some old furniture with some vintage inspiration, or even spicing up some old picture frames or mirrors to give them a gorgeous vintage patina.

using air-dry clay with decorative moulds
Tip #1: Choose the right moulds & clay
My first top tip is to choose the right molds and clay for your projects. My favourite molds are the Iron Orchid Design molds, and that’s because they have gorgeous designs, and each mold has a raised edge, as well as an exact measurement that really makes a big difference. You can find them at my dear friends store, Rustic Ranch, in Airdrie, Alberta or online here.

Top quality air-dry clay
Choosing a good quality clay or resin really helps to hold the fine detail and decreases shrinking and cracking of your project. I use the IOD air-dry clay but I have tried other kinds and they work well too. If I had to choose where to spend my money, I’d go with the IOD moulds and use a more affordable clay.

Tip #2: use a scale to minimize waste & cost
If you choose the IOD molds, using a scale will help you minimize waste. This will make a huge difference to cost if you’re doing a large project.

Tip #3: store clay in an air-tight container
Make sure to always store your clay in an airtight container, even in between making individual molds. It dries out extremely fast and a dry clay will not work in silicone moulds.

USEFUL MATERIALS
- Iron Orchid Designs (IOD)Air-Dry Clay
- IOD Clay Molds:
- Bench Scraper
- Plastic Wrap
- Tite Bond – Quick & Thick Glue
- Dry Paint Brush
Tip #4: PREPPING SILICONE MOULDS
Use a paint brush to apply a little tapioca starch (or any other starch) to your mold before adding your clay. This really helps to prevent sticking and makes de-moulding way easier. so just paint it on and then tap the excess off.

Tip #5: Plastic wrap is your friend
Tip number five is to use plastic wrap to smooth the clay and keep it moist while you work on getting that clay into the mould. This is a super easy tip that is really helpful because if you get pulled away from your project, you don’t have to worry about your clay drying out.
It also really helps to create that perfectly smooth back for the glue to adhere to.

Tip #6: How to get clean edges
My next tip is to use starch to clean the edges. I use tapioca starch but any other starch will do, like corn starch or arrowroot powder.
This is where those iron orchid (IOD) molds are really superior. As that raised edge just allows you to rub your finger along or use a little tool like this palette knife to just quickly clean off the edges and make it perfect.

Tip #7: De-moulding trick
The plastic wrap comes in handy again when de-molding. Put your plastic wrap on top and then just give it a little smack on the countertop. This way it won’t come flying out and stretch when you’re removing it. It will just gently fall out and be perfect.

Tip #8: smoothing out edges
Use a plastic or silicone palette knife to just run along the edges and clean them up. This will give your clay mould a perfectly clean edge.

Tip #9: creating gorgeous designs with clay moulds
Tip number nine is to lay out your design before gluing and to try mixing and matching moulds. Try using a palette knife to isolate pieces of the mould that you like, and then combine different moulds together in order to get your own unique design.
Laying it out before gluing like this allows you to play with pieces from different molds and create a beautiful design.

Tip #10: tips for gluing your project
When gluing your project. I recommend using that palette knife to just gently move the glue all around the back surface. You don’t need a lot of glue if you put it on correctly.
Then use a measuring tape to make sure that you’ve centred your piece exactly where you want it on your project, and gently press down without squishing the clay at all and pushing it really gently in towards the rest of the project.
When the glue and clay dries, it will begin to pull away from the other pieces. So giving that gentle squish helps a lot.
I also like to clean up any excess glue that has oozed off the edges. This’ll make for a nice clean edge.

Tip #11: creating perfect corners
If you have corners in your project, like I did here in this mirror frame I was finishing. Use a palette knife to cut the pieces of the clay at a 45 degree angle on both sides before then gluing it down. Then you can use a straight edge to make sure that all those pieces are perfectly lined up at a 90 degree angle to the other corner.

Tip #12: Finishing to create smooth designs
Sometimes you want a really vintage look with lots of cracks and spaces. However, sometimes you might want a smooth finish, like in my French-Inspired Wall Paneling.
If this is the case in your project. Take some clay to fill in any cracks that may have happened, and use your palette knife to just kind of smooth it out. You can use either a silicone one or a plastic one like I’m using here.

Then when there are spots where the clay has lifted up off of the surface, use some silicone based paintable caulking. Cut the tip at a 45 degree angle, point that angle towards the surface you want the silicone to be in and squeeze it in.
Then immediately use a wet finger and a wipe and just wipe the excess off. Remember to use this caulking once your clay has dried, and in an hour you can paint your surface.

Tip #13: finishing with paint and wax
My last tip is to use a lighter tone of paint in combination with different color waxes, to highlight all those beautiful accents that you’ve made. I’ll show you how I did this and another project coming up soon.
